摘要
讨论了在变频状态下利用信号多普勒信息的波达方向估计问题，提出了在此状态下的时—空域联合处理方法和时—空域级联处理方法，并与在变频状态下的常规空域处理方法进行了比较。分析及仿真结果表明。
The DOA estimation using signal′s Doppler information in frequency agile state is discussed in this paper. Two methods, spatial-temporal joint processing method and spatial-temporal sequential processing method, are presented here. The performance of these two methods are compared with that of the conventional ML method in frequency agile state. Analyzing and simulation results show that the methods using signal's Doppler information have a significant performance improvement compared with conventional ML method.
